Study of Bacillus Calmette-Guerin (BCG) Combined With PANVAC Versus BCG Alone in Adults With High Grade Non-Muscle Invasive Bladder Cancer Who Failed At Least 1 Course of BCG
United States32 participantsStarted 2013-12-18
Plain-language summary
Background:
\- Many cancers produce two particular proteins. The immune system can target these to attack the cancer. The PANVAC vaccine puts genes for these proteins inside a virus vaccine so the body sees the proteins as foreign invaders and attacks them. Researchers will test PANVAC on people with high grade non-muscle invasive bladder cancer. They will give it to people who have not responded to the usual treatment, bacillus Calmette-Guerin (BCG) over several weeks. They want to see if PANVAC plus BCG is better than BCG alone.
Objective:
\- To compare the effects of PANVAC plus BCG therapy, to BCG therapy alone.
Eligibility:
\- Adults 18 and older with high grade non-muscle invasive bladder cancer who failed at least 1 course of BCG.
Design:
* Participants will be screened with blood and urine tests and abdominal scans.
* Participants will be randomly assigned to get BCG only or BCG plus PANVAC.
* They will have up to 10 visits over 15 weeks. Most of these are part of usual cancer care.
* They will have blood and urine tests.
* All participants will get BCG in 6 weekly injections.
* One group will also get PANVAC in 5 injections over 15 weeks.
* Between weeks 17 and 20, participants will undergo tests of the tumor area as part of their usual care. They will have cystoscopy, exam under anesthesia, and bladder biopsy. Results will be used to evaluate the different treatments.
* Participants will have quarterly follow-up visits for up to 2 years.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
✓.1.1.1 Patients must have histologically confirmed localized high grade (G3) transitional cell carcinoma (urothelial carcinoma) of the bladder that is stage Ta, T1, and/or carcinoma in-situ (CIS) confirmed by the Laboratory of Pathology, National Cancer Institute (NCI) 45 days prior to study entry. This can be obtained at an outside hospital prior to entry into the study or at the NCI. However, all outside pathology specimens will require that the formalin-fixed paraffin embedded tissues be re-read by the Laboratory of Pathology, NCI. For patients enrolled at collaborating trial sites, diagnosis must be confirmed by the Department of Pathology at the institution where the patient is enrolled on the trial.
✓.1.1.2 Patients have failed at least one previous induction course of intravesical Bacillus Calmette-Guerin (BCG), defined as histologically confirmed persistent or relapsing tumor present on post-BCG endoscopic evaluation. All BCG failures will be considered for inclusion into the study, including BCG-refractory, -resistant, and relapsing, as defined in the Rationale and Background. For the purposes of the study, BCG-refractory and BCG-resistant subjects will be considered to have BCG-persistent disease.
✓.1.1.3 Patients who are not currently candidates for radical cystectomy (e.g. patient refuses surgery, comorbidities preclude major surgery, etc.).
✓.1.1.4 Age \>18 years.
✓-Because no dosing or adverse event data are currently available on the use of BCG in combination with PANVAC in patients \<18 years of age, children are excluded from this study.
What they're measuring
1
Percentage of Participants Without Recurrence (Recurrence-free Survival (RFS)) With Bacillus Calmette-Guerin (BCG) + PANVAC Compared With BCG Alone at 6 and 12 Months
Timeframe: Assessed from start of therapy to 6 and 12 months following therapy
✓.1.1.5 Eastern Cooperative Oncology Group (ECOG) performance status \<2.
✓.1.1.6 Patients must have normal organ and marrow function as defined below:
✓.1.1.7 Computerized Tomography (CT) urogram or Magnetic Resonance Imaging (MRI) urogram. If urogram protocol not available or contrast allergy/poor renal function preclude such imaging, then noncontrast CT or MRI of the abdomen/pelvis within 45 days of study entry will suffice.
Exclusion criteria
✕.1.2.1 Previous pelvic radiation for bladder or prostate cancer if performed \<12 months prior to enrollment into the study.
✕.1.2.2 Patients who are receiving any other concurrent investigational agents (patients are eligible to enroll 4 weeks after completion of prior agent).
✕.1.2.3 Patients who have had chemotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier. There will be at least a 3 week delay from the time of a previous bladder biopsy/transurethral resection of bladder tumor (TURBT) to allow for adequate bladder healing prior to enrollment.
✕.1.2.4 Patients with a history of encephalitis, multiple sclerosis, or seizures within the last year (from seizure disorder or brain metastasis) should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
✕.1.2.5 History of allergy or untoward reaction to prior vaccination with vaccinia virus
✕.1.2.6 Patients should have no evidence of being immunocompromised as listed below:
✕.1.2.7 Uncontrolled intercurrent illness which would interfere with the ability of the patient to carry out the treatment program, including, but not limited to, active second malignancy other than a cancer that has been successfully treated resulting in a high likelihood of long-term survival (e.g. completely resected basal cell or squamous cell carcinoma of the skin, stage 1 renal cell carcinoma treated with partial nephrectomy, treated low risk prostate cancer, etc.), inflammatory bowel disease (e.g. Crohn's disease or ulcerative colitis), active diverticulitis, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
✕.1.2.8 Pregnant women are excluded from this study because the vaccines used in the study may have the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with the vaccine, breastfeeding should be discontinued if the mother is treated with vaccines. These potential risks may also apply to other agents used in this study. Patients must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while her partner is participating in this study, she should inform her treating physician immediately
